It's not much, at least not compared to what he grew up to, but he's hoping that given the thought he's put into picking it out, that she'll really like it. He knows that he's screwed up, especially this last week, which is why he rubs a hand through his hair as he looks at her. "I know my āiyā mouth has screwed things up, but Kaylee Frye, will you accept my apology and love me through all the times inevitably to come?"
Not much? It's perfect and beyond beautiful. It's the most perfect little ring that he could have gotten for her. It suits her and it makes her grin brightly. She pokes him in the side. "'Course. Wouldn't stop lovin' y'just because you're a big dummy," she says, offering him her hand. Sure, it's dirty, and grimy but that's what he's asking for asking Kaylee to be his wife.
